Communication System Redundant Path Selection via Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wide area wireless communication networks, when trouble occurs at one base station, communication apparatuses struggle to maintain connectivity unless they switch to a redundant communication path, and selecting redundant paths via the same base station leads to traffic congestion, especially when multiple apparatuses choose paths through a single base station without issues.
Innovation Solution
A communication system where a server receives attribute information from communication apparatuses connected via different base stations, generates path setting information, and enables the first communication apparatus to set a redundant communication path through a second communication apparatus and its base station, considering the attributes and carriers of the second base station, thereby avoiding traffic congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication apparatuses select redundant paths via the same base station, then communication connectivity is maintained, but traffic congestion occurs
Solution Approach 1:
The patent applies local quality by making each communication apparatus select redundant paths based on its own local conditions (which base stations are currently connected to). The server generates path setting information tailored to each apparatus's specific situation, ensuring that apparatuses connected to different base stations choose different redundant paths, thereby distributing traffic locally rather than concentrating it at a single base station.
Solution Approach 2:
The server performs preliminary action by proactively generating and distributing path setting information to communication apparatuses before failures occur. This pre-computed path information includes attributes of alternative base stations, allowing apparatuses to immediately switch to appropriate redundant paths when needed, avoiding the need to make congestion decisions in real-time during failures.
2Object-affected harmful factors
If a server generates path setting information considering base station attributes, then traffic congestion is avoided, but system complexity increases
Solution Approach 1:
The server acts as an intermediary that centralizes the complex task of analyzing base station attributes and generating optimal path settings. Instead of each communication apparatus independently analyzing network conditions and making complex decisions, the server performs this analysis centrally and distributes simplified path setting information to apparatuses, reducing the computational burden and complexity at the network edge devices.

AI summary
A communication system includes a first communication apparatus connected to a network by a first communication path running via a first base station, a second communication apparatus connected to the network by a second communication path running via a second base station, and a server configured to be capable of communicating with each of the first communication apparatus and the second communication apparatus. The second communication apparatus is configured to transmit to the server, attribute information indicating an attribute of the second communication path including the second base station, the server is configured to generate path setting information for the first communication apparatus to set a communication path, on the basis of the received attribute information, and the first communication apparatus is configured to set a redundant communication path running via the second communication apparatus and the second base station, based on path setting information generated by the server.
